Summary

We report here about measurements of resistance vs. temperature, alternating current (a.c.) susceptibility and X-ray diffraction performed on Ba2Sr2Ca2Cu3Ox superconductor doped with various amounts of Pb. The results could be explained in terms of Pb contribution in increasing both the amount of the highest T C 0 phase and connectivity between superconductive regions. The Pb substitution on Bi sites is also discussed.
